TROLLEY- GUARD.

Specification of Letters Patent.

Patented May 28,1912.

Application filed May 29, 1911. Serial No. 630,250.

To all whom it may concern:

Be it known that I, HOWARD H. MONEIL, citizenof the United States,residing at New Freedom, in the county of York and State ofPennsylvania, have invented certain new and useful Improvements inTrolley- Guards, of which the following is a specification.

This invention relates to trolley guards.

The object of the invention is to provide a trolley guard embodying suchcharacteristics that lateral displacement of the trolley wheel withrespect to the trolley wire is reduced to a minimum and embodying amongother characteristics means whereby the positioning of the trolley wheelwith relation to the trolley wire or conductor is facilitated so thatthe trolley wheel may be readily engaged with the trolley wire indaylight or darkness.

l/Vith the above and other objects in view the present inventionconsists in the combination and arrangement of parts hereinafter morefully described, illustrated in the accompanying drawings, andparticularly pointed out in the appended claims, it being understoodthat changes may be made in the form, proportion, size and minor detailswithout departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawings: Figure 1 is a side elevation of the invention. Fig. 2is a top plan view. Fig. 3 is a detail view of one of the guard arms.Fig. 1 is a side elevation of the invention with the casing on one sideof the device removed.

Referring now more particularly to the accompanying drawings thereference character 10 indicates the upper portion of a trolley pole towhich I secure in any suitable manner a substantially U-shaped yoke 11in the legs of which at the free ends thereof is journaled a trolleywheel 12 adapted for engagement with the trolley wire 13 in the usualmanner and for the usual purposes.

Secured preferably to the journal 14 on which the wheel 12 is disposed,one on each side of the wheel 12, is a curved arm 15, each arm beingdirected upwardly from the yoke and curved rearwardly and downwardly, asshown. These curved arms have pivotal movement on the journal 14 andhave their free ends preferably perforated at 16 to receive one end of ahelical or other spring 17, the opposite ends of the springs 17 beingpreferably connected in the eyes 18 of the legs of the yoke.

To facilitate the engagement of the wheel 12 with the trolley wire orconductor 13 I secure to each arm 14 an inwardly directed projection 19,the inner edges of the projections converging so that the trolley wireor conductor 13 will slide down between the projections and becomeseated on the trolley wheel 12, whereby the trolley wheel is easily'andquickly positioned with respect to the trolley wire": In one embodimentof the invention the projections 19 may be formed of wire or similarmaterial with each end connected to its respective curved arm or if acasing, such as 20, incloses the arms and the springs to exclude ice,sleetand other foreign matter, the upper ends of the projections may besecured to such casings, by means of bolts 20 on the outer ends of whichare secured nuts 19. It will thus be understood that the projections 19form means for facilitating positioning of the trolley wheel withrespect to the trolley wire and that the curved arms serve as guards andwith their projections 19 tend to prevent lateral displacement of thewheel with respect to the trolley wire. The springs 17 permityieldability so that if the device should strike braces on the poles(not shown) the several parts of the device will be caused to assumetheir original positions without stopping the car to replace them. Forinstance, by virtue of the pivotal mounting of the curved arms 15 theymay wind around on their pivots against the action of the springs 17which latter become compressed upon backward movement of the arms andwhich are released and expand immediately upon pressure being taken fromthe forward end of the arms, there be ing a stop 21 formed on each arm15 for engagement with the corresponding leg of the yoke to limit theforward movement of the arms and this forward movement may be reinforcedby the inner end of the casing 20 being formed to provide a supplementalstop 22 designated to engage the corresponding leg of the yoke.

From the foregoing it will be seen that I provide a simple, inexpensive,durable and eflicient device for connection with a trolley pole toexpedite the placing of the wheel on the trolley wire or conductorwhether in daylight or darkness and to prevent displacement of the wheelfrom the trolley wire or conductor when going around curves or in theevent of striking obstructions such as connectors between poles and thetrolley Wires, the device having yieldable parts which positionthemselves automatically by virtue of which yieldability is permittedwhen the wheel strikes connections between the poles and wires withoutderanging the various parts, they assuming their normal positionsautomatically.

What is claimed is:

A device of the character described comprising a yoke, a wheel mountedin the yoke, a pair of arms secured to the ournal of the Wheel, springconnections between the free ends of the arms and the yoke and guidemembers carried by the arms, the springs cushioning the arms in onedirection of their movement and the arms having stops for engagementwith the yoke to limit the movement of the arms in the oppositedirection and a casing disposed over each arm and having a part thereofforming a projection for engagement with the yoke to reinforce theaforesaid stopping means.

In testimony whereof I affix my signature in presence of two witnesses.
